ABSTRACT

Raga Similarity had been a topic of fascination among Karnatik music followers. Though the topic remains active and interesting, a lack of appropriate similarity quantification method leads to subjective interpretations which in turn can be ambiguous intermittently. In this paper, we propose a raga similarity method, RagaDist, that quantifies similarities between raga pairs, based on their semantic structure and classifies the similarity into a 4-scale measure. Similarities derived using RagaDist is compared with popular string similarity methods using clustering approaches – Hierarchical clustering and Partition Around Medoids (PAM) and Multi-Dimensional Scaling (MDS) methods to analyze emerging patterns and characteristics among Melakarta raga similarities. Empirical measurements were conducted using one-way ANOVA and post hoc analysis. We also determined that using RagaDist, a threshold of 0.79 may be used as a cut off to distinguish ragas based on similarity.
